#include <stdio.h>

int main()
{
    int i = 1, 2, 3;
    
    printf("%d", i);
    
    return 0;
}

(A) 1

(B) 3
(C) Garbage value
(D) Compile time error

Answer: (D)
Explanation: Comma acts as a separator here. The compiler creates an integer variable and initializes it with 1. The compiler fails to create integer variable 2 because 2 is not a valid identifier.
